X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3f9b5a7ffa75871b238f931af37f8f595e998838;p=u-boot.git

drivers: video: tidss: tidss_drv: Change remove method

Change remove method of DSS video driver to disable video port instead
of performing a soft reset, as soft reset takes longer duration. Video
port is disabled by setting enable bit of video port to 0.
